Thanks for sharing this, it’s really interesting 
I remember a similar method was used to enable the new Siri UI on devices that didn’t support Apple Intelligence during the iOS 18.1 beta. Apple patched it pretty quickly, though.
Over the past few years, Apple has significantly hardened iOS against jailbreaks. Blocking tools like Nugget shows they’re still actively closing off ways for third-party software to modify or interact with the system in unintended ways.
It’s kind of nostalgic, actually. Years ago, the jailbreak community was incredibly active. These days it’s much quieter, but at the same time iOS has become far more customizable than it used to be, so I guess that has changed the landscape quite a bit.
